To all about it may concern:

ie it known that I, ALBERT C: Masons, a

' citizen of the- United States residinv at ';Memphis, in the county ofShelby and tate by the operation'of the inlet TfllYGiS so of Tennessee,have invented certain new and useful Improvements in Inlet-Valves fortimed as to pern'iit. the full compressive above type,

action oi-the "mainpistonyupon the explosive mixture to be'obta': and*generally to improve and sim p1i nlet ivalves' of the To this end,'mv;inention is'embodied in preferable form :in the device hereinafterdescribed and illustrated in "the accompany ingdrawings.

In the'drawm'g the "figure a sectional the piston valve and alsothrou gha special form ;of speed rgulating 'distributer. interrnediate' {thepiston -valve and the carbucrank 6 ofthe main crankshaft 7.

The casing 14communicates with a chamber-16 formed bya suitable casing or shelland'communieating with a suitable ,carbujreter. The chamber16 is adaptedto contain a special regulating and gas distributing device thepedififl1ti62l of Letters Patent.

specific construction of--.\vliich need not be here described as itformsthe-subject matter of another application executed by me. The piston 13is hollow and is adapted to receive a charge of the explosive mixturefrom the carbureter through the distributing chamber at each suctionimpulse of the main piston and said pistonis rovided with one or moretransverse va re 'ports 17 through its wall, which ports are adapted oregister \in' the reciprocal movement of the piston valve with' theports 18 formed in a circumferential lining member19 withm the cylinder15. The cylinder 15 is cored out to form a longitudinal passage way 20between the cylinder wall and lining and .:pr 'ovi dingcommunicationbetween the ports "18 and one or more outer portsfllv formed 'inthelining member 19.; The lining mem 'ber 19 provides an effective means ofob taining accurately cut ports at a minimum expense and avoiding theinaccuracy and the. expense required by forming such ports hv coring theshell of the cylinder wall -1tseif. i

The main piston and the piston valve are shown, 1n the drawing at themoment when themain' piston is descending on the down suction stroke andwith this position of the mar: pistonthe inlet valve is' so located thatthe ports 17 in the piston valve are in registry with' .the' ports 18 inthe iining;

thus permitting the explosive mixture as it is drawn into the piston bythe'suction of the main piston to pass through the ports 18 and passageway 20 and thence through ports 21 from whence the charge is drawnthrough the passage Way'22leading from the pis on valve cylinder to themain'cylinder. inward or toward the main crank shaft while the pistonvalve at the same time continues. to-moveioutward' or .awayfrom ihe mainpiston continues to moveits crank shaft and the outward movement of thelatter is-continued during the return compressioni stroke of the-mainpiston'and by the time the main piston'starts to comv press the charge,,the ports '18 and 21 will e-coveredby' the piston vali'e and .by thetime. the comprcssion stroke is com leted and .at the :proper timefor-the exp osion of-the compressed charge the piston valve will-beatthe outer end of its stroke with .its Outer face flush with the outerend-of the cylinder. Any suitable form .of exhailst' valve may beemployed in connection with the device. Similarly, th'e'piston' valvemakes one inward. movement, that is a just about to begin its-intake"movement,
